Y To all lwhom t may conceal/vv.:

Be it known that I, HENRY L. PITMAN, a citizen of the 'United States2residing in Westeld, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in Typewriting"Machines, of which the following is a specilication. i

This invention relates to the application of mechanism of the continuousbilling or fan-foldetype to a bookkeeping machine -of theUnderwood-Hanson type and is in the nature of an improvement on theinventions disclosed in the applications of B. C. Stickney, Serial No.489,990, filed August 5, 1921, and Serial No. 562,969, filed May 23,1922.

When tan-foldv mechanism is applied to a bookkeeping machine of'the typereferred to, the webs must be guided above certain 4 20 parts of the'computing mechanism located at the. rear of the typewriter-carriage andusually piojecting somewhat above the rear edge of the paper-tableforming part oisid carriage. The usual webs are, therefore, in- 2 5troduced at such a height above the platen that it is ditlicult tostraighten them sutliciently to retract the carbons. Furtherdifficultiesarise in providing for access to the` the rear of thetypewriter-carriage, and in providing means for supporting the rail onwhich the rearward extension of the carriage travels.

The main object of the invention is to pro- .35 )vide new and improvedmeans for avoiding the above and other diiiicultiesarising from theapplication of fan-fold mechanism to bookkeeping machines.

. In the embodiment of the invention herein disclosed, use is made .ateach end ofqthe denomination-selectorsand other parts at platen of anoversized broad pinion for connectmg a gear .on the-adjacent end of theplaten-axle with a similar gear on a stub shaft journaled in theadjacent end of the carriage. By using the over-sized broad pin- `ions,it is rendered possible to locate the axis, about which the broadpinions turn and about which zthe platen-lifting frame swings, at suchan elevation that the platen may be displaced upwardly to la greater`extent than in the ordinary 'fan-fold machine.

' In the usual form of fan-fold machines, the endsof the platen-liftingframe are connectedby a tie-member or rod which 'extends along the axisabbut which the platen-lifting frame swings. If, however, thistie-member were used in the machine embodying the present invention, itwould interfere bothv with the view f thework being typed and also' withthe handlingof work .extending around the platen. To avoid suchobjections, the usual'tie-member is lomitted and, in its place,provision is madevof a tie-member or rod connecting the ends of theplatenlifting frame behind the usual 'collating table and adjacenttheplaten. It will be evident that a tie-rod in the position describedwill not interfere in any way with the view of the work and accessthereto. l

The rearward extension of the carriage on which the usual carbon-carrieris mounted may consist of a.' continuous apron or guard extending overthe denomination-selecting mechanism at the rear of thetypewritercarriage and having its forward edge adjacent the upper edgeofythe rear paper-table,

'and may be so mounted on a' rail at the rear .guids the webs to therear vpaper-table, the

remainder of the extension being cut away' to make the structurelighter, and being provided at its side and rear edges with lianges tostiil'en it. Provision may be made of rails of the usual type' securedto the upper face of the extension and serving to support and guide theusual carbon-carrier.

The rear rail, upon which the carbon-car- I rier-extension of thecarriage is supported, maybe heldin position by brackets connected tothe usual stand on which lthe bookkeeping-machine rests, the connectionbe-' tween the rearward extension of the carriage and the rail beingsuch that the former may be swung upwardly aboutthe latter. In

from being swung too far upwardly and rearwardly, provision is made ofsuitable means to prevent such excessive movement. Such preventing meansmay be of any suitforder to prevent the rearward' extension able form,such as a chain connected at one end to the 4extension and at the otherend to the stand of the bookkeeping machine, Sullicient slack beingprovided to vpermit the necessary amount of swingof said rearwardextension.

Provision may also be made for locking the rearward extension of thecarriage in its normal position.

ln order that friction between the rearward extension of the carriageand the rail on which the rear extenslon rests at lts rear may bediminished, provision may be made of suitable friction-reducing means,such as ball-bearing-mountings vfor the wheels run- ,ning on said rail.Provision may also be made of means associated with said mountings tohold the rearward extension of the carriage on the rear rail when it isswung upwardly.

Other features and advantages will hereinafter appear.

A platen 11 is revolubly mounted in a carriage 12 supported at its frontby a roller 13;,projecting into a groove in a cross-bar 14C, and at itsrear b a rail 15, said crossbar 1t and rail V15 eing xed on atypewriter-frame 16.

The typewriter-frame 16 is mounted on a computer 17, which, in turn,rests on a stand 18, comprising4 a top 19 and'legs 20. To insure properpositioning of the computer 17 on the stand 18, the top 19 is providedwith socket-members 21, having taered openings 2-2, into which ittapered feet 23 of the computer. llt will be evident that the movementof the tapered feet 23 into the socket-members 21 will insure the properpositioning of the computer 17 on the stand 18.

Provision is made at the rear of the carriage of a rear paper-table 24:and rearwardly-exte'nding brackets 25 to support a rack 26 to receive,at letter-space distances, a tabulator-stop 27. Projecting outwardlyandupwardly from the rear ends of brackets 25 are brackets 28, in whichare supported the ends of a rod 29, on which a d enomination-selector 30is mounted for swinging and sliding movements, the selector being heldin any selected letter-space position along the rod 29 by means vof atooth 31 engaging in the proper notch of a series in a rod 32, saidnotches being at letter-space distances apart along said rod 32. lltshould be` understood that, although reference has been made to onetabulatorstop and one denomination-selector, a plurality of each ofthese elements may be used when required.

A denominational jack-housing 33 is supported at the rear of, and above,the denomination-selector 30 by means oit a transverse bar 34 supportedby brackets 35 extending rearwardly and upwardly from thetypewriter-frame. Extending downwardly from the rear of thedenominational jackhousing 33 to the lower rear portion of the computer17 isa casing 36 for the usual thrust-rods, not shown. Obviously,`aplurality o? sets of jacks and housings therefor may be provided, and,as shown in Figure 6, the machine herein disclosed is a three-registermachine and has three sets of jacks and three housings.

rllhe computing mechanism and the denomination-selecting mechanism,forming part thereof, maybe, in general, similar to that disclosed inthe patent to Richard M. Becker, Non. 1,296,355,` granted March el,1919. The present invention Jcontemplates the application of tan-foldmechanism to 4a bookkeeping machine, such as that of which llO v'apartial description has been given; To

A ably curved to guide the web 39 over the 49 to assist in positiomng astop, not shown,-

13, to reduce the weight, L its side-and rear edgesA housing 33, andother parts at the rear of the upper edgeof the rear paper-table 24. Atthe rear of the continuous portion 41, the extension 37 is cut away, asshown in Figure with flanges 42 to strengthen it.

Mounted alng the edges of the extension 37 are rails 43, which serve toguide and support the carbon-carrier 38. Preferably the rails 43 arespaced rom'the upper surface of the extension 37 -by means of spacers orwashers 44, at suitable intervals, and the rails are secured to theextension bymeans' of screws 45 passing through' openings 46 and throughthe spacers 44 into threaded openings 47 in said extension. Thecarboncarrier 38 may be supported on the rails 43v by grooved rolls 48pivoted on the carboncarrier 38, and engaging the'rails 43 on oppositesides thereof. As shown in Figures 1f and 13, the forward screw 45 forthe lefthand rail may bev provided with a head which will projectupwardly above the surface-of the rail to serve as a stop to limit theforward movement of the carbon-carrier; and, as shown in Figure 5,lthe-lefthand rail 43 may be vprovided with a scale for limiting therearward movement of the carbon-carrier 38.

In the normal operation of the machme,

y the extension 37 travels with the carriage 12, and for such movementruns on a rail 50, v

positioned beneath the same and near the @cercar edge thereof. Therai1-50 is attached at its front to lips 51 formed on plates 52 securedto the upper ends of brackets 53, s

which are secured at their lower ends fto the top 19 of the stand 18 onwhich the bookkeeplng machine rests. Each of the bracks ets 53 is formedas a channel-iron and gradually increases in size -from its upper -endto its lower end, where it is attached to the stand 18. Preferably, aportion of each bracket at the base of the channel is cut away todiminish the weight. At their lower ends the brackets 53 are formeel soas to fit around the upper surface of the top 19 and the rear surface ofa downwardly-extending flange 54 forming part of the top and isprovidedat 19, each bracket conhfected near their lower ends by a bar57,

for a purpose tobe described hereinafter.

4'.lo avoid unnecessary friction between the extension 37 andthe rail 50as the former travels, along the latter, provision may be made, at eachside of the extension, 37, of a pair of cones or rolls 58, each having afrusto-conical portion 59 to run on the rail 50. The rolls 58 ofeachpair are annular in form and are mountedby suitable ballbearings ona block 60, secured to the adjacent side liange 42 by any suitablemeans, such as screws 61. Passing through the block 60 is a bolt 62,threaded at each end and carrying at each side of the block 6() a coneor bearing member 63, havin a conical surface, to co-operate with ba ls64 in a groove or raceway 65 of the adjacent roll 58 mounted on thebolt62, and, at the outer side of each of the rolls 58, a cone or bearingmember 66 having an inwardly-facing conical surface,to engage the balls64 on the side opposite to that engagedvby the corresponding member 63,the parts being held in position by means of nuts 67 on opposite ends ofthe bolt 62. lt will be seen that each pair of rolls 58 serves to give abearing extending around. a suiicient portionof the raiA 50 to avoid atendency to run oil the rai 50.

To insure engagement lbetween each pair of rolls 58 and the platen,provision is made of a member 68 having a horizontal portion 69 held-by, a screw 7() against a shoulder 71 formed by cutting away a portionof the uper part of the block 604 at its inner\ end.

ach member 68 also comprises a portion extending 'down' the inner faceof the correspending block 60, and secured theretoby a screw 72, and a`curved portion 73 extendlng around' the rail y50 to the vbottom thereof.It will be lseen that the extension 37 is so mounted on the rail 50 thatit may be swung upwardly and rearwardly about said rail 50 without beingdisconnected therefrom, thereby permitting access to thedenominationselecting mechanism at the rear of the carriage to permitadjustment of the parts, such as the positioning ofthe-denominationselecting mechanism- 30 along the rods 29 and 32. Theextension 37 may be swung from its normal position, shown in'Figure 1, v

to the position .shown in Figure 12, the upward movement of theextension being limited preferably by means of a', chain 74 lllconnected at its lower end to the bar 57,

which connects thev rail-supporting brackets, and, at its upper end, toa rlng 75 surrounding a rod 76, which is connected at its ends with theside flanges 42 of the extension 37.

lltshould be understood that the chain 741 is ot' sutiicient length sothat the extension, when in its limiting position, Figure 12,

`will be held in such position by means ot means to lock the forward endof the extension to the carriage 12. 'lo this end, provision is made ofbrackets 77 and ot suitable bearing-members 78 secured to the upper endsof said brackets 77. As shown in Figures 8 and 9, the bearing-members 78have circular openings 79 in allgnment with each other, and each of saidmembers 78 is provided with a vertical slot 80 extending downwardly fromits upper surface to the circular opening 79, the width of the slotv80being less than the diameter of the circular openings 79. To co-operatewith the bearing-members 7 8, provision is made of a vshaft 81, mountedin brackets 82, attached to the portion 41 of the extension 37 on theunder side thereof, the shaft 81 being ot suitable diameter to fit inthe openings 79 of the bearing-members 78, and being cut awa on oppositesides thereof near its ends, to orm flats 81a, so that, when the shaftis in proper rotative position, the cut-away ends may be passed throughthe slots 80 in the bearingmembers 78, as indicated in Figure 8, and

turned to, the position indicated in Figure 9, thereby locking theextension 37 to the carriage 12.

Normally, the shaft 81 is urged in a locking direction by means ot aspring 8d connected, as shown in Figure 5, at its left end to the shaft81, and at its right end with the extension 37. To limit the movementorn the shaft 81 in opposite directions, provision is made oit arcuatemembers extending partially around the shaft 81 adjacent the brackets 82and secured to the shaft 81 by any suitable means, such as screws 88: Asshown in Figure 8, the forward end of each 'i member 85, when broughtinto contact with the lower surface of the guard t1, will position theshaft 81 so as to permit its removal from the bearing-members 78, theshat, when released to the action ot the spring 84e,

being turned tothe locking position shown in Figure 9, with the otherends ot the members 85 contacting with the portion 11. At-its outerends, the shaft 81 is provided with collars 87 contacting. with theouter surfaces of the bearingfmembers 78, and also with collars 88engaging Athe bearing-mem bers 78 at the inner sides thereof rlhecollars 87 and 88 may be detachably secured on the shaft 81 by screws87a and 88a, respectively. l Y

Preferably, the left-hand collar 88 is provided with a finger 89, whichmay serve as alignment Meafiee a lett side gage or guide tor workpassing over the extension 37 to the rear paper-table. Provision is alsomade ot a finger or guide 90 projecting from the right-hand collar 88.Preferably, the linger 90 1s ot greater length than the finger 89 andmay serve not only as a right side gage or guide :tor the work, but alsoas a finger-piece for turning the shalt 81 against the action ot thespring 8d to the position shown in Figure 8, so that the rearwardextension 37 ot the carriage may be swung upwardly to the position'shown in Figure 12.

At the rear oit/the extension 37 ot the carp riage, the web passes overa rod or guide 91 immediately above therear edge of the extension, andthe web may be guided at its side edges by yside guides or gages 92, otwhich the left gage is provided with an overhanging portion 93 toprevent the adjacent edge of the web from being thrown above the top ofthe guide. Fach of the gages or guides 92 is provided with a collar 9d,which may be secured to the rod 91 at any desired 4position therealongby means ot a set-screw 95. Preferably, the rody 91 is provided with adepression 96, for each position to which the guides are to be adjusted,said depressions being of suitable size to receive the lower ends ot theset-screws 95. rl`he outer depressions are so positioned as to locatethe side gages 92 substantially in with the respective fingers 89 and90. Each end of the rod 91 is secured to an upright arm 97 ot a bracket97, having a horizontal arm 98 lying against the lower surface ot theextension 37 and secured thereto by any suitable means, such as rivets99. lt Wi l be seen that side flanges 42 are cut away near their rearends to permit the passage of the horizontal a'rms 98 of the bracket97a. l

As -shown in Figure 1, the forward ends of the flanges a2 of theextension 37 are cut away to form inclined edges following the generaloutline of the top of the housing 33, thereby permitting the extension37 to be placed lower llt should also be noted that the guard 111 isarched upwardly above the plane of the main portion of the extension 37so as to ass over the upper edge of the housing 33. he arrangement justdescribed is such that the web 39, in passing over raised very slightlyabove the forward edge ot the housing 33, and that the portion of theextension on which lthe carbon-carrier 38 runs is lower guide to such anextent that the web 39 will pass substantially horizontally from thecarbon-carrier 38 toA andover the guard 411.

Notwithstanding that the lan-fold mechanism at the rear of the carriageis so designed as to guide the web 39 over the denomlnation-selectingmechanism at as low lll() than could otherwise be done.

llfi

the guard L11, is

than the top portion ot the A ganarse a level as possible, it isnecessary to displace the platen 11 upwardly to a greaterv extent thanin the ordinary fan-fold machine, to permit the web 39 to bestraightened .underthe 2laten. To this erd, provision is made o suitablebars or members 100, secured to ends 101 of a 'platen-frame 102 formingpart of the carriage 12. The members 100 lie against the inner faces ofthe ends 101 and may be secured to said ends by means including bolts103 inserted Jfrom the inside of mem-bers 100 through openings in themembers 100 and ends 101 and threaded into nuts 104 on the outer sidesof the ends 101. inasmuch as the platen is to be lifted to an abnormalextent, each one of the members 100 is provided at its forward end withan upwardly'and forwardly projecting bracket 105 to provide suitablepivotal supports rfor the ends 106 of a platendisplacing frame 107. Theends 106 of the platen-displacing frame 107 have arms sub.- stantiallyat right angles to each other, one arm 109 of each of said ends 106being pivoted to the adjacent bracket 105, and the platen 11 beingsupported in said frame 107 by means of a platen-axle 108 journaled inthe ends 106 substantially at the vertices of the right angles formed bythe arms 109 and 110 of the ends 106. The arms 110 are joined by atie-member 111 and, when the platen-displacing frame 107 is in itsnormal position with the supports 112 at the outer ends of the arms 110resting on a shaft 113l extending across the carriage at the rear of therear paper-table 24, studs or pins 111a projecting from the arms 110will be engaged and held by hooks 114 fixed on the shaft 113 which isnormally urged by a spring 115 to effective position, thus lockvlng theframe 107 in its normal position.

The hooks 114 may be swung rearwardly to ineiective position, whendesired, by means of' a linger-piece 115a extending upwardly from theleft-hand hook.

To turnthe platen, provision is made of a gear 116 fixed on each end ofthe platen-axle 108D just outside of the adjacentoend 106 of thedisplacing frame 107; and of a similar gear/117 fixed on the .inner endof a stubshaft 118 journaled in the adjacent end of the carriage inalignment with the norma-l position of the platen-axle. Both of thegears 116A and'117 areconstantly in mesh with a broad pinion 119 mountedcoaxially with the pivots about which the platen-displacing frame 107swings so that the connection between the gears 116 and 117 and thebroad pinions 119 will be maintained, irrespective of the position ofthe platen-displacing frame. The laten may be rotated by means offinger-w eels 120 on the stub-v shafts 118, or by suitable line-spacingmechanism, not shown. Due to the provisions `for displacing the platenupwardly to an abstill prevent access to the slotted heads 121l of thebolts orf-'screws 103. rll`his difficulty is overcome, .hweveix byproviding openings 122 in gears 117, so that, when the latter arerotated to theproper positions by one of the finger-wheels 120 orotherwise, a suitable tool; such as a screw-driver, may be passedthrough either one of the openings 122 and engaged in the slot of thecorresponding head 121 and the screw, forming part of the latter, turnedas desired.

Preferably the mounting of each end 106 of the platen-displacing frame107 and of the adjacent broad pinion 119 is as follows: A. bushing 123is secured in an opening 12d of the adjacent bracket 105, and throughacentral opening in said bushing isfinserted a bolt or screw 125, whichext/ends through the hub 126 of the broad p'inion 119 and is providedwith a threaded end 127 of reduced size, which is screwed tightly -intoa boss 128 fastened on the adjacent lend 106 of the platen-displacingframe. llt should be understood that the pinion 119 turns freely on saidbolt 125.

lin fan-fold machinesv of the usual form,

the ends 106 of the platen-displacing frame 107 are joined by atie-member substantially coaxial with the pivots about which theplaten-displacing frame swings. Due to the abnormal height, withreference to the platen, of the pivots (screws 125) of theplaten-displacing frame, a tie-member of the usual form would interferewith the View of the work. According to the present invention, no. suchtie-member is used, and` to stillen the platen-displacing frameotherwise, provision is made of a tie-rod 129 connecting the two ends106 and passing to the rear of the usual collating. table 130 and closeto the platen. A gage-bar 131 of the usual form is secured to the backof the collat'ing table 130, and is provided lwith'an adjustableend-gauge 132 of the usual form.

Provision is made of a knife 133, piv- 'otally mounted on theplaten-axle, to facilitate the tearing-od' of used sections of the web,and'preferably the knife, instead of being flat, as in the usual form,is turned away from the platen at its rear. edgeto form a flange134,-thus keeping the knife `Suciently strong, while decreasing itswidth and thereby avoiding interference with the view of the .work bythe rear edge of the knife. The' knife 133 is supported on arms 135pivotally mounted on the platen-.axle and may be swung away from theplaten 11 by means of a finger-piece 136 (Figure 5)'. 1

Furthermore, the arrangement of the various parts to permit the abnormalupward displacement of the platen renders it inconvenient to limit theforward position of the platen-displacing frame 107 in the usu'al mannerby resilient stop-members extending upwardly from the transverse bar 137at the front of and forming part of the carriage 12. Fro'vision istherefore made of brackets 138, one at each side of the carriage,secured at their forward ends to the bar 137 by any suitable means, suchas screws 139, and at their rear ends fitting over the hubs 126 of thebroad pinions 119. Each ,f n

having a platen, a carriage therefor, comprising a forwardly anddownwardly inof the brackets 138 is provided with an upward extension atits rear end, said upward extension having a tooth 140 projectingytherefrom to engage the forward edge of the arm 109 'of the adjacent endof the platen-displacing frame 107, to'stop the latter in the positionshown in Figure 1.

`When it is desired to set a denominationselector 30 to determine theposition of a computing. zone, the finger-piece 115a is shoved to therear to release the platen-displacing frame 107 from the hooks 114, andthe frame 107 is swung forwardly to the position shown in Figure 1. Thefinger or finger-piece 90 is then pushed to the rear to turn the shaft81 to its releasing position shownin Figure 4, so that the rearwardextension 37 of the carriage may be swung upwardly until it reaches itslimiting position determined by the ,chain 74, as shown in Figure 12;the length of the chain being such that the extension 37, when swungl toits Figure 12 position, will be held in such position by gravity. Thedenomination-selector 30 may then be swung upwardly about the rod 29,and adjusted therealong, as shown in Figure 12. "When such adjustment iscompleted, the denomination-selector is swung down to the osition showniILFigure 1, and the Aextension 37 restored to and locked in its normalposition.

lt will be evident that, according to the present embodiment of theinvention, provision has been made of means for the purpose describedwhich enables the web to be fed over the raised itorward edges of thehousings 33 at a very slight distance thereabove, and that the new partsare so designed @as to be readily applicable to fanfold machines now inuse.
